Potentiometer Calculator

Potentiometer refers to an instrument for measuring an unknown voltage by comparison to a standard voltage. A three-terminal resistor with an adjustable center connection, widely used for volume control in radio and television is termed as a potentiometer. A potentiometer is also called as a variable resistor or pot.

Potentiometer is a type of variable resistor that resists electric current and adjusts electrical devices. A potentiometer is similar to a rheostat, but it is more efficient. The advanced online Potentiometer Calculator is used to calculate the divider voltage for three terminal resistors.
